  • Patent number: 6199490
    Abstract: A telescoping table with a base and at least two slides and a support table, which can be displaced linearly on it in a telescoping manner, and with drive devices assigned to these components, is to be operated in such a way that, even at small degrees of extension, at least the support table is fully or almost fully extended on the slide which guides it, and, to the extent possible, the second slide is also extended relatively far forward on the first slide, the required drive devices being installed in readily accessible and easy-to-maintain locations. For this purpose, it is proposed that the base be equipped with two drive devices, the first of which is connected only to the first slide, whereas the second operates tension cables, tension belts, tension bands, tension chains, and/or lengths of chain which operate a second slide or a second slide plus additional slides as well as the support table.
